多源自主导航系统完备性研究

Research on Completeness of Multi⁃source Autonomous Navigation System

多源自主导航系统技术是新一代国家综合定位、导航与授时(Positioning,Navigation and Timing,PNT)体系下终端用户导航系统的技术发展方向。聚焦于导航系统综合评估的完备性,分析了完备性理论构建存在的科学技术问题,基于任务场景、运动环境以及载体动力学特征等,提出了多源自主导航系统中的指标体系构建和建模表征、指标间归一化处理和组合权重动态分配、指标综合的完备性度量与全回路动态迭代优化的解决方案,为多源自主导航系统技术体系构建打下基础。

Multi⁃source autonomous navigation system technology is the technical development direction of end⁃user navigation systems under the national positioning,navigation,and timing(PNT)system.The completeness in the compre⁃hensive assessment of navigation systems is focused on,and the scientific and technical problems in constructing the com⁃pleteness theory are analyzed.Based on the task scenario,motion environment,and carrier dynamics characteristics,solu⁃tions for the construction and modeling characterization of the index system,the normalization processing and dynamic as⁃signment of the combination weights among the indexes,and the completeness assessment and full⁃loop dynamic iterative optimization under indexes synthesis for the multi⁃source autonomous navigation system completeness theory are proposed,laying a solid foundation for the technology system construction of the multi⁃source autonomous navigation system.
